Answer the following showing all work.

1. A compound that is 40.0% C, 53.4% O, and 6.6% H. The molar mass of the compound is 120.grams. Find the EF and MF ?



























2. Find the MF for the following: EF = CH2O1. Molar mass = 240.g/mole






















3. Find the MF for the following: EF = Hg1Cl1. Molar mass = 472g/mole.


















4. A compound that is 54.5% C, 31.8% N and 13.6% H. The molar mass of the compound is 88 grams. Find the EF and MF ?





















Answers:1)MF = C4H8O4 and EF = C1H2O1, 2)MF = C8H16O8, 3)MF = Hg2Cl2, 4)MF = C4H12N2 and EF = C2H6N1
